INVENTOR. Hyman Freedman BY 7/ r United States Patent 3,430,669 FILLINGMEANS FOR DENTAL SPRAY BOTTLES Hyman Freedman, 200 W. 58th St., NewYork, N.Y. 10019 Filed Aug. 20, 1965, Ser. No. 481,352 US. Cl. 141-353Int. Cl. B67c 3/28; G02b /08 1 Claim ABSTRACT OF THE DISCLOSURE Thisinvention relates to dental implements, and more particularly to thoseof the type which are disclosed in my Patents Nos. 2,720,702 and3,001,288. In those patents are shown dental mirrors provided withfluid-spraying means, and the present invention has reference to meansfor providing a spray in a certain relation to a dental mirror; to meansfor associating the mirror with a spray nozzle; to means for pivotallymounting the spray nozzle in company with the mirror, and to means forsimplifying the filling of a spray bottle with water or other fluid.

It is an object of the invention to provide a dental mirror arrangementin which the mirror is attached, removably or permanently, to a spraynozzle, with the spray nozzle so disposed that the fluid ejected from itwill be projected across the face of the mirror and sub stantiallyparallel to the plane of said face. The spray nozzle and the attachedmirror are pivotally mounted between the spray tubes of the implement,thereby providing for a pivotal adjustment of the nozzle and mirror as aunit while constantly maintaining the relative positions of the mirrorand nozzle with respect to one another and regardless of the position towhich the nozzle and mirror unit is pivotally moved.

It is another object of the invention to provide a simplified means forfilling a water or fluid receptacle to which a fluid-using dental tool,such as a mirror, is attached. In presentpractice, the filling of aspray bottle of the above-mentioned kind involves the unscrewing of acap from the bottle and the filling of the bottle through its open top.The present invention contemplates the opening of a valve in afluid-supply line by the thrust of a filler tu-be attached to the cap ofthe bottle and while said cap remains in position on the top of thebottle, so that the water or other fluid will flow into the bottlethrough the cap without requiring removal of the cap from the top of thebottle.

With these and other objects to be hereinafter set forth in view, I havedevised the arrangement of parts to be described and more particularlypointed out in the claim appended hereto.

In thev accompanying drawings, wherein illustrative embodiments of theinvention are disclosed,

FIG. 1 is a front elevational view of a portion of a dental mirrorholder provided with spraying means in accordance with the invention;

FIG. 2 is a side elevational view of the same;

FIG. 3 is a side elevational view of a detachable mirror;

FIG. 4 is a side elevational view of the spray nozzle 3,430,669 PatentedMar. 4, 1969 provided with a socket for the reception of the stem or thedetachable mirror shown in FIG. 3;

FIG. 5 is a top plan view of the nozzle and attached mirror socket asseen on the line S5 of FIG. 4, looking in the direction of the arrowsand showing the stem of the mirror in place in the socket;

FIG. 6 is a sectional view through the valve device for controlling thewater or liquid flow into the container or spray bottle;

FIG. 7 shows the parts of FIG. 6 as they appear when the valve is closedbut is in readiness for opening by pressure imposed on its stem by theinsertion of the filler tube on the cap of the fluid receptacle, and

FIG. 8 is a sectional view, taken substantially on the line 88 of FIG.6, looking in the direction of the arrows.

Referring to the drawings, and particularly to FIGS. 1 to 4 thereof,there is shown therein a dental appliance in the form of a dental mirror1, provided at its rear with a projecting stem 2 which, in theembodiment shown in FIGS. 1 and 2, is fixedly attached to a spray nozzle3. The nozzle may be of known form, such as shown for example in myPatent No. 3,001,288 and it is provided with an outlet or jet opening 4which directs a fluid or water spray across the face of the mirror 1.Another outlet or jet for the fluid is shown at 6 from which a spray 7is ejected on the tooth or area in which the dental work is in progress.The spray ejected across the face of the mirror is shown at 5.

At 8 is shown a water supply tube and 9 shows the air supply tube, thesetwo tubes extending in side-by-side relation and are held together bymeans of the clamp 10. At their upper or forward ends the tubes 8 and 9embrace the nozzle 3 between them, the nozzle and hence the mirror 1attached thereto, being rotatively or pivotally mounted between theinturned ends 11 of the tubes 8 and 9.

The nozzle is so positioned relatively to the plane of the mirror thatthe spray 5 emanating from the jet outlet 4, is directed substantiallyparallel to and across the face of the mirror to cleanse the same, sincethe outlet end of the jet opening 4 is located close to the peripheraledge of the mirror and is so directed that it directs its spray acrossthe face of the mirror.

By means of the disclosed arrangement, the mirror and the nozzle, beingsecured together as a unit, are maintained as a unit in a specificrelationship so. that the spray emanating from the nozzle is constant asto direction in relation to the mirror. The unitary pivoting of themirror and nozzle permits the mirror to be swung to any desired positionrequired for the work being performed and with the assurance that thespray emanating from the nozzle will always be best directed for notonly cleaning the mirror but for also cleaning the seat of dentaloperations.

In the embodiment of FIGS. 1 and 2, the mirror is shown as beingpermanently attached to the rotative nozzle. In FIGS. 3 and 5 the stemof the mirror is shown as being removably fitted within a socket 12 thatis fixedly attached to the nozzle. As seen in FIG. 5, the socket may bein the form of a split ring and it frictionally engages the stem 2 ofthe mirror with sufiicient gripping force to hold it from bothlongitudinally shifting or becoming rotatively displaced.

In FIGS. 6 to 8 inclusive is disclosed an arrangement for filling afluid container, such as the water bottle or similar receptacle that isused in connection with such dental appliances which spray water orother fluid, such as for example, the mirror appliance shown in FIGS. 1to 5. In this arrangement, the water and air tubes 8 and 9 respectivelyenter into a head 13 which is rotatively mounted in a cap 14 threadablyreceived in or on top of a ferrule 15 secured by cement or otherwise tothe top of a bottle 16 or similar container as used on a dental tool.

The cap 14 carries a siphon tube 17 which extends intO the bottle andthe water 18 or other fluid is drawn upwardly in the usual mannerthrough the tube 17 for expulsion out of the spray outlets 4 and 6 asshown in FIG. 2.

One of the objections encountered by the dentist in using an arrangementof this kind is the procedure involved in filling the bottle. Thisrequires the unthreading of the cap 14 and its removal from the top ofthe bottle; the pouring of the water into the bottle and then thereplacement of the cap. The present invention contemplates theelimination of this method of filling the bottle.

Fixed in and extending through the ferrule 15 is a tube 19 which has apart projecting into the ferrule above the top of the bottle neck, andhas another part, shown at 19a located on the outside of the ferrule andprojecting radially from the same.

The bottle-filling device includes a flexible tube connected to andextending from a source of water or other fluid to be delivered into thebottle. The tube is fitted at its outlet end with a sleeve 22, which isinternally threaded to receive a valve 23. The valve 23 may be any oneof numerous types and that which is illustrated in FIG. and foundsatisfactory for the purpose is the widely used tire valve. Such a valveused in millions of automobile and bicycle tires includes a stem 24which when depressed, will cause the opening of the valve and will holdit open as long as the pressure is maintained on the stem 24.

Provided in the free end of the sleeve 22 is a tubular nipple 25 whichserves as a guide for the portion 19a of the filler tube 19. Thebottle-filling procedure is a simple one since it consists in merelyinserting the part 19a of the filler tube 19 into the guide nipple 25and by such insertion causing the end of the part 19a to come intocontact with the end of the stem 24 and depress said stem to therebyopen the valve 23. The water or other fluid under pressure is forcedthrough the tubing 21 from its source, and which water might be thatobtained from a tap, and will be forced through the sleeve 22, past theopen valve 23 and will flow through the tiller tube 19 to enter and fillthe bottle. Thus, when the bottle needs filling, the dentist need notinterrupt his work for a substantial period such as that required tofill the bottle in the usual way, but need only depress the valve stem24 by the push of the tube 19 against it to secure a flow of the waterinto the bottle. The valve will, of course, close to shut oif the waterflow upon the cessation of the pressure by the tube 19 on the stem 24.

While I have herein mentioned the described device as being applicablefor the filling of the bottle with water, it can be used for the supplyof air, or valves of the kind described can also be used for the supplyof carbon dioxide or other compressible gas. Valves of the kinddescribed can be used in pairs or in multiple to interchangeably supplyair or water or both. Also, while I have described the receptacle 16 asbeing a bottle, the same might be a bulb or flexible bag or othersuitable container.

While I have herein described embodiments of the invention, it isobvious that the same is not to be restricted to the specificarrangements disclosed, but is broad enough to cover all structurescoming within the scope of the annexed claim.

What I claim is:

1. A filling device for the spray bottle of a dental implement, thebottle having a cap provided with means for fitting it on the top ofsuch a bottle, a fixed filler tube extending radially through the capabove the mouth of the bottle on which the cap is fitted, said tubehaving a portion located and exposed on the outside of the cap, afluid-supply conduit terminating in a sleeve containing a normallyclosed valve having a valve stem which, when depressed by contact withthe end of the exposed part of the filler tube, will cause opening ofthe valve, a guide nipple on the end of the sleeve for slidable fitmentover the exposed part of the filler tube to cause the valve stem to beguided into contact with the end of the filler tube by the slidablemovement of the nipple over the exposed part of the filler tube andcause opening of the valve to provide the flow of fluid past the valveand through the filler tube to enter the bottle.
